Overview
Pcb is an open-source printed circuit board by ju90092, from the ju90092/pcb repository on GitHub. It is a 2-layer board of 100 × 104 mm with 7 parts on 13 nets, routed with 77 tracks and 0 vias.
It is built around the DHT11. Its parts include 2 ICs, 2 connectors, 2 switches and 1 resistor. It belongs with the ESP32 and RISC-V boards of this library.
Main components
1README
README.mdIt was the first time that I made a PCB and, even though I had a hard time connecting everything, it was really fun. I used KiCad and I looked online for the things I couldn't find on Hack Club's guide. This PCB was made with the intention of being like a Tamagotchi, where you have a little virtual pet to play with. To make different versions of the pet, I used LibreSprite, which is an app where you can draw pixel art. You can check them in the PNG archives of this project. The PCB has this format because I really like math and, when I was searching for fractals, it appeared in a math question on the OBMEP site (one of the most important Brazilian math olympiads). I think the pets I liked the most were the pink bird and the porcupine.

Questions
How big is the Pcb PCB?
It measures 100 × 104 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pcb use?
7 parts, built around the DHT11. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Pcb KiCad files?
From the ju90092/pcb repository on GitHub, at the commit this page was made from: the board is Pcb.kicad_pcb and its schematic Pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask ju90092 before reusing the design.
